I'm using an OMAP-L137. Can the ARM9 call a codec _control function while the _process function for the same codec is running? I'm thinking this could be useful for asynchronous mode changes.
In a related vein, I would like two codecs to share memory. Some of this memory needs to be external memory (because it consists of huge data buffers). Another part is quite small and could exist in Shared Memory or some DSP local memory. Has anyone out there sent the same memory buffers to two different codecs? Does it work? If not, has anyone used DSP "globals" between two codecs?
